Dual–Acceptor Engineering in Pyrene‐Based Covalent Organic Frameworks for Boosting Photocatalytic Hydrogen Evolution

Abstract The integration of electron donor (D) and acceptor (A) units into covalent organic frameworks (COFs) has received increasing interest due to its potential for efficient photocatalytic hydrogen (H 2 ) evolution from water. Nevertheless, the advancement of D–A COFs is still constrained by the limited investigations on acceptor engineering, which enables the highly effective charge transfer pathways in COFs to deliver photoexcited electrons in a preferential orientation to enhance photocatalytic performance. Herein, two systems with D–A and D–A–A configurations based on the acceptor molecular engineering strategy are proposed to construct three distinct COFs. Specifically, TAPPy‐DBTDP‐COF merging one…
